* Simply set XXX_UNKNOWN on output parameter.
V2:
- Add call to register volume_raid_info
- Add LSM_CAP_VOLUMERAID_INFO to capabilties
Changes in V3:
* Use lsm_register_plugin_v1_2() to register lsm_volume_raid_info() support.
Changes in V5(no change in V4):
* Sync API changes:
* argument name 'disk_count'
* argument type 'uint32_t'.
* constant name 'LSM_VOLUME_DISK_COUNT_UNKNOWN'.
